Question 1

How does Anthemis cotula work as an emmenagogue?

Accepted Answer

Anthemis cotula contains sesquiterpene lactones, anthemic acid, and anthecotulid, which are thought to stimulate uterine contractions and promote menstrual flow. These compounds may also possess anti-inflammatory properties that could explain its traditional use for rheumatism. However, the exact mechanism of action has not been well studied in clinical trials (Evidence Level C). The plant's characteristic pungent odor and insect-repellent properties are attributed to its volatile oil content.

Question 2

Does Anthemis cotula interact with any medications?

Accepted Answer

There are no well-documented drug interactions for Anthemis cotula in the scientific literature. However, due to its traditional use as an emmenagogue, it may theoretically interact with hormonal medications, blood thinners, or drugs affecting uterine function. Given the limited research and known potential for adverse skin reactions, individuals taking prescription medications should avoid this herb. Consult a qualified healthcare provider before considering any herbal supplement.

Question 3

What is the recommended dosage for Anthemis cotula?

Accepted Answer

There is no established safe or effective dosage for Anthemis cotula in modern herbal practice. Traditional preparations varied widely, but due to its documented potential to cause severe skin irritation and blistering, internal use is not recommended. The evidence supporting any therapeutic use is limited (Evidence Level C). Most herbal practitioners advise avoiding this herb entirely in favor of safer chamomile species such as Matricaria chamomilla.

Question 4

Is Anthemis cotula safe during pregnancy?

Accepted Answer

Anthemis cotula is contraindicated during pregnancy and should be strictly avoided. As a traditional emmenagogue, it has been used historically to stimulate menstrual flow and may induce uterine contractions, posing a risk of miscarriage. Additionally, its potential to cause skin irritation and allergic reactions makes it unsafe for topical application during pregnancy. Pregnant individuals should use only herbs approved by a qualified healthcare provider.

Question 5

What are the side effects of Anthemis cotula?

Accepted Answer

Anthemis cotula is known as a strong skin irritant and can cause contact dermatitis, redness, itching, and blistering upon skin contact. This reaction is primarily due to sesquiterpene lactones present in the plant. Individuals with Asteraceae (daisy family) allergies are at particular risk of severe reactions. Internal use may cause gastrointestinal upset. Due to these safety concerns and limited therapeutic evidence, this herb is rarely recommended in modern herbal practice.

Question 6

What is Anthemis cotula used for traditionally?

Accepted Answer

Anthemis cotula, also called stinking mayweed, has been used traditionally as an insect repellent, for menstrual disorders, and for rheumatic complaints. However, these uses are based on folk medicine rather than clinical research (Evidence Level C). Unlike German chamomile (Matricaria chamomilla), Anthemis cotula is not commonly used in modern herbalism due to its potential to cause skin irritation and blistering. Safer alternatives are generally recommended for similar therapeutic purposes.
